Observability Slosv1.0.0

Define SLOs for the checkout journey to ensure high conversion. SLIs include availability and latency of payment processing, and error budget policy freezes feature releases when budget is exhausted.

Set SLOs for user login, a critical path. Use multi-window burn rate alerts to page on fast budget consumption, with quarterly review to adjust targets as user base grows.

Define SLIs for API sync latency and success rate. Tier dependencies like payment gateways and set realistic SLO targets capped by vendor SLAs, with error budget policy for rollbacks.

Create SLOs for video start time and buffering ratio. Use proxy SLIs from synthetic probes if client-side metrics are unavailable, and review quarterly as CDN configurations change.

Use event processing lag as SLI for batch systems. Set SLO target windows aligned with batch run cadence, and error budget policy to prioritize reliability over new features when lag spikes.

Use SLOs to justify pricing tiers (e.g., 99.9% for premium, 99.5% for basic). Error budget policy freezes feature development for low-tier if budget exhausts, protecting premium user experience.

Set SLOs on checkout and payment to minimize lost revenue. Rapid burn alerts trigger immediate rollback of risky changes, preserving conversion rates and revenue.

Define SLOs for ad delivery and content loading. Advertisers rely on uptime, so error budget policy escalates to engineering before breaching ad-serving SLAs.
